Smoking and Wrinkles

The wrinkle risk was particularly strong for people who had smoked heavily
for many years.

"We examined nonfacial skin that was protected from the sun, and found
that the total number of packs of cigarettes smoked per day and the total years
a person has smoked were linked with the amount of skin damage a person
experienced," Helfrich says in a University of Michigan news release.

The study doesn't prove that smoking caused or worsened wrinkles. But the
results held when the researchers took other factors, including participants'
age, into account.
